Good answers above for what kind of people you want, but I'm thinking you might also want some structure as to what a team and job descriptions might look like?
In larger quality teams, I've seen QA broken out into 3 subdivisions that work well. Operations, Compliance and Documentation, and Systems/Inventory.
As a fellow 1-man operation looking to expand, my first hire is actually going to be an intern whom I'll pass on many QA "maintenance" tasks like sample preparation, calibration, document control, etc. with some special projects for them to help me with.
Moving from a 1 person department to multiple in baby steps, I would bring on these types of positions first as you grow.
Document Control and office generalist: this person will help you maintain all your documentation not just in SOP's, but daily verification/review, supplier maintenance, inventory/traceability troubleshooting, etc. It's a moderate pay position and will free up a ton of time on your end. Depending on the available workload, they can also handle product release and systems.
Quality control technician/QC assistant/QC Auditor: this person is technical support for QA, helping you perform internal audit activities, lab and equipment maintenance/calibration, and inspecting resolving issues and holds for things happening on the floor.
These positions will rely on your regulatory compliance expertise and final management decisions on the programs they're supporting/implementing, but help take some of the "day-to-day" as you move from a primary workload position to a supervisory position. The last person to add will be a higher salary compliance person responsible for much of the regulatory research and maintenance (licensing, etc.) that you're doing right now. But I would add them last due to cost and the available workload for such a position.
Also, if you're currently also doing R&D for your company as QA (like many small companies), you may also suggest bringing on a food scientist to perform those tasks to free you up for QA.
